A Specification of Letters Patent. L I Pirtentgd fllav 25. 1 Q20,

Application filed April 22, 1919. Serial No. 291,835.

To all whom it may conccrn:

Be it known that I, Annnii'r E. LOGAN, a. citizen of the- United States, 'residin at Brooklyn, in the county of Kings and tate of New York, have invented which the following is a specification,

This invention relates to automobile wheel rims and more p'articularlyto an improvement in demountable rims for supporting clencher tires. I

The primary object of the present invention is to provide a rim to which the tire may be readily and conveniently fitted and from which it may be equally as readily removed thus avoiding the tedious and laborious workingof a tire from its rim as is at present necessary where the rims are of integral or one piece structure. I Briefly stated the rim embodying the present invention comprises two annular sections disposable edge to edge, and it is one object oi' the present invention to provide novel means for locking these sections in their assembled relation so that they cannot become relatively laterally-{i'splaced or separated. 1;,

Another object of the invention is to provide means for preventing'dust entering between the meeting edges of the two rim sections.

A further obiect of the invention is to provide means whereb ;-one section may be z-aused to rotate with relation to the other section in the event the locking means hecomes rusted or clogged to an extent to prevent ready relative rotation of the sections merely by hand.

in the accompanying drawings:

Figure l is a'perspective view of the rim embodying the present invention; Fig. 2 is a fragmentary sectional perspective view illustrating the sections of the rim in position about to be assembled;

.Fig. 3 is a transverse sectional view through the rim in the plane of one of the vided for preventing entrancltof dust anddirt betweenthe meeting edges-oi the sec-- tions. i a

The wheel rim embodies two sections one indicated in general by the numeral 1 and the other in general by the numeral 2, the

certainnew and useful Improvements in il vheel-Rims, of

section 1 being preferably although not necessarily the wider section. Each of these sections is of annular form and is provided 5 at its outer lateral edge with the usual flange '3 to engage the tire bead. In other words, these. two sections have the form of the parts which would result if the ordinary rim were split circumferentially, Consequently in order to adapt the rim for use, it is necessary that the inner lateral edges of the two sections be brought into mutually abutting relation as shown most clearly in Figs. 1 and 3 of, the drawings. This 13, of course, ac-

complished after the sections have had their.

flanges 3 engaged with the opposite beads of the tire casing to be supported upon the rim, held thus assembled, which will now be described.

The section 1 at suitable intervals in its circumference, is formed in its inner side with recesses i which have the general form of-the well-known bayonet slot, each recess having the lateral extension 5 which in this instance extends in the direction'of the circumference of the rim section. These recesses 4 open inwardly through the inner lateral-edgeof the said section 1 and are designed to receive locking heads 6 formed at corresponding intervals circumferentially upon the corresponding or inner lateral edge of the section 2 as clearly shown in Figs. 2 and 3 of the drawings, the locking heads 6 being each provided. with a lateral exten sion or nose 7 and the recesses i at their ends which 0 en through the inner lateral edge of the section 1 being of a width suiiicient to permit of the entrance oi the nose carrying ends of the said locking heads 6 when the rim sections are brought together laterally. \Vhen the sections are brought together in this manner the locking heads will, of course, enter the recesses 4L, and then if the sections are relatively'rotated, the noses 7 oh the said locking heads will be caused to enter the extensions 5 of the respective recesses .and by reason of their engagement in these extensions of the recesses will eiiectually lock the two sections of the rim againstrelative lateral separation. Of course, in removing the tire from the rim the sections are to be relatively rotated in the reverse direction so that the noses of the locking heads will recede from the extensions 5. of

and in order that the sections may be means is prov ded siliency of the supported tire .wiil serve to laterally projecting continuous flange 9,

which, when the sections are assembled, is designed to seat snugly within the ,said groove or channel 8 thus effectually closing the space which would otherwise be present to a greater or less degree between the meeting edges of the said sections.

In order that the section of the rim may be rotated with relation to the section 1 in the event the locking means heretofore described become clogged or stick for any other reason so as to render such rotation like'so as to loosen the parts.

Having thus described the invent-ion what is claimed-as new is:

A tire rim including wide and narrow annular sections having means for engaging the head of a tire, the meeting edges of said sections being provided with an interfitting continuous tongue and groove, said wide section being provided with bayonet slots in its inner face, L-shaped locking lugs carried by the inner edge of said narrow section and adapted to be received within said bay onet slots, said bayonet slots and said. E.- shaped locking lugs being spzg ced inwardly from the outer face of the rim to provide a smooth bearing surface for aftire, and a striking device 'arried by one of saidsections and projecting laterally from the same.

In testimony whereof I afiix my signature.
